RGB Mini-LED TVs offer impressive picture quality, but their prices remain high. That may change. Global Technology has begun work on a new RGB BAR backlight module that is intended to significantly simplify the construction of TVs. The manufacturer says it will reduce the number of driver ICs by as much as two thirds!
The new solution uses Time Sharing Operating (TSO) technology, that is, time-division multiplexing. In practice this means a single 12-channel driver can sequentially drive several LEDs instead of requiring separate drivers for each. According to Global Technology, the number of driver chips can thus be reduced by up to 67%. In addition, the simplified wiring allows the use of cheaper single-layer printed circuit boards.
Cheaper RGB Mini LED as early as 2027?
RGB LED technology uses separate red, green and blue backlight LEDs. This allows televisions to offer a wider colour gamut than traditional LCD designs with a single-colour backlight. The larger number of control elements, however, makes their production more complex and costly. RGB BAR is intended to help solve this problem. The company plans to begin mass production in 2027, and in future wants to use the solution in monitors and automotive displays as well.
Does this mean cheaper RGB Mini LED televisions? Not necessarily straight away. Lower manufacturing costs could, however, make it easier for manufacturers to introduce the technology into more affordable models.
